Soil nutrients were analyzed, including soil organic matter, total N, total P, total K and available nutrients concentrations. The results showed that the orchard soil pH was 8.32 on average, which means they were alkaline soil. Total P and available P concentrations were relatively rich, others, such as soil organic matter, total N, hydrolyzable N, total K, available K concentrations, were relatively low or in the medium levels. Additionally, soil nutrient concentrations varied among different sampling locations. For example, the concentrations of soil organic matter, total N, total P were the highest in Sunlou, with the concentrations of 14.11 g？kg-1, 1.09 g？kg-1, and 1.04 g？kg-1, respectively. While the concentrations of total K and available K were the highest in Songlou with the concentrations of 19.38 g？kg-1 and 114.73 g？kg-1. Although the concentrations of soil nutrients were low, they significantly increased compared with the data of the concentrations from the second general soil survey due to balanced fertilization technology and the implementation of the fertile soil engineering %K 丰县 %K 果园 %K 土壤养分 %K 二次土壤普查< %K br> %K Feng county %K apple orchard %K soil nutrient %K second general soil survey %U http://xblxb.paperopen.com/oa/darticle.aspx?type=view&id=201502011
